Method and system of calculating distance to empty of each vehicle drive mode

A system for calculating a distance to empty (DTE) of vehicle drive modes of a vehicle, comprising:

• a memory configured to store program instructions;
• and
• a processor configured to execute the program instructions, the program instructions when executed configured to:
• in response to receiving a driver selection as a drive mode and accumulating a drive distance of the selected drive mode while a vehicle is being driven in the selected mode, collect drive data including an accumulated drive distance of each drive mode, and fuel efficiency information of each drive mode of an eco mode, a comfort mode, a normal mode, and a sport mode;
• calculate a final fuel efficiency of each drive mode using a drive distance of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode, a consumption energy of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode or a fuel efficiency of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode, and a learning fuel efficiency obtained by performing learning while the vehicle is being driven;
• and
• calculate a DTE of each drive mode based on the calculated final fuel efficiency of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode.

A method of calculating a distance to empty (DTE) of vehicle drive modes of a vehicle, comprising:

• in response to receiving a driver selection as a drive mode and accumulating a drive distance of the selected drive mode while a vehicle is being driven in the selected mode, collecting, by a controller, drive data including an accumulated drive distance of each drive mode of an eco mode, a comfort mode, a normal mode, and a sport mode, and fuel efficiency information of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode;
• calculating, by the controller, a final fuel efficiency of each drive mode using a drive distance of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode, a consumption energy of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode or a fuel efficiency of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode, and a learning fuel efficiency obtained by performing learning while the vehicle is being driven;
• calculating, by the controller, a DTE of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode based on the calculated final fuel efficiency of each drive mode of the eco mode, the comfort mode, the normal mode, and the sport mode, and
• displaying, in response to a control signal output from the controller, on a display device a DTE of a mode that corresponds to the driver selection of the drive mode among the calculated DTEs of the respective drive modes,
• wherein the final fuel efficiency of each drive mode is calculated by performing blending for the actual drive fuel efficiency of the each drive mode and for the learning fuel efficiency of each drive mode according to a ratio of the total drive distance of each drive mode to the drive distance of each drive mode, using the formula below,
